Chemical Use by Pregnant Laboratory Workers

Certain chemicals are
known or suspected to harm fetuses or reproductive health of adults. Some examples
of reproductive toxins are: anesthetic gases, arsenic and certain arsenic compounds,
benzene, cadmium and certain cadmium compounds, carbon disulfide, ethylene
glycol monomethyl and ethyl ethers, ethylene oxide, lead compounds, mercury
compounds, toluene, vinyl chloride, xylene, and formamide. The first trimester
of pregnancy is a period of high susceptibility. Often a woman does not know
that she is pregnant during this period. Individuals of childbearing potential
are warned to be especially cautious when working with such reproductive toxins.
These individuals must use appropriate protective apparel (especially gloves)
to prevent skin contact. Pregnant women and women intending to become pregnant
should seek advice from knowledgeable sources before working with substances
that are suspected to be reproductive toxins. These sources include but are
not limited to the respective Laboratory Supervisor, Material Safety Data Sheets,
and the UK Environmental Health and Safety office. Notify supervisors of all
incidents of exposure or spills; consult a qualified physician when appropriate.
